Israel has killed less than 1% of all Palestinians, so your bullshit logic is just that.
To add insult to your stupidity, the median age in gaza is 19 years, which makes the 60% number actually a good thing since 75% of the population is either a woman or a child.
If they wanted to actually kill civilians, why is the death count such a low percentage of the population?
It would be trivial for them to be killing more, and yet they aren’t.
